Moving 2003 Email Stores to a Fresh Install of 2003

Hi,
I tried to google this subject but didn't get good results. Is there a
way to import the mailstores/ keys / users / ect... and load them into
a fresh install of Windows 2003 Server and 2003 Exchange?

We've had some corruption of the boot drive and mail stores. We
replaced a bad hard drive causing the errors on the array ... but
suspect that there has been damage to the OS. We had to repair the
database afterwards.
